When I compare the scores with HD5570 scores on the Internet, it seems a bit slower (sometimes much slower) -- I understand most benchmark reviews use a very fast CPU system (whereas here it's an old E6420 only), but then I don't think the E6420 should be bottlenecking the HD5570 a lot to have significantly slower scores.
(compared for instance: <click here for link>
where the test setup used a Core i7-920 and got these scores:
3DMark03 = 24194
3DMark05 = 13798
3DMark06 = 7275 )

I notice this PowerColor Radeon HD5570 has a slightly slower memory clock than the reference HD5570:
this HD5570 has only 667mhz GDDR3 memory (=1334mhz effective rate)
whereas the reference Radeon HD5570 is supposed to be 800mhz = 1600mhz effective rate
while some Radeon HD5570 actually have 900mhz = 1800mhz effective rate.

But not only that.
I notice that based on GPU-Z and other specs info,
the Radeon HD5570 is supposed to have 400 stream / unified shader processors.
Whereas this PowerColor HD5570 has only 320 stream / unified shader processors (assuming GPU-Z is correct).

Can someone else post the GPU-Z screenshot of their Radeon HD5570 for comparison purposes?
(specifically I'm interested to find out if the Sapphire Radeon HD5570 has similar specs since they have similar price)

Not sure but it does seems like a weak card. I ran 3dmark 03 on my 4870 just for kicks a giggles today. I didn't change anything just installed and hit the run benchmark button. I got 45k out of it. My card also has 16 rops and 800 shaders with a 256 bit bus width.

note that mine actually says 5570 and yours says 5500 series.. maybe yours isnt a 5570, but 5550
you sure its a 5570?

but if my card is 5550 why the rops only 4?
fyi 5550 have 8rops

is that my card is really exist? the card with 4rops, 320sp,?
is that possible the brand E.G powercolor cut down the gpu features like rops or stream proc? or AMD make new version 5570 with TURKS gpu but cut down version of Turks ,

This is one of three threads you have made about this on this forum. (One as dta even.) One thread is sufficient. If you are unhappy with what was sent to you, speak with PowerColor and/or your place of purchase.

We know this is correct because the photo's show the "same Serial Number" on the card

lol same thread and TS... i replied on the older one though. didn't saw this one... anyways, i tried to bring this up with Sapphire forums, nobody could provide a clear explanation to this "false advertising"..

this shit again ... guy is obviously trying to discredit power-color .. might I suggest a subnet ban
his fault he bought from a shady retailer this thing looks like NO power color 5570 I can find ANY WARE tlDR he bought a fake and is mad crying shame NOT power colors problemhttp://www.powercolor.com/us/products_layer_2.asp?SeriesID=57

anyways as to the question about sapphire -> powercolor... literally of course both are different video card manufacturers... but what they have in common is on their HD5570 DD3 product. with the information i've gathered around while i was away, i learned 2 versions of the said video card were released. the first few batch of the video cards were the real HD5570 (based on hardware specs). some time in Q4 of 2009, the "slow" HD5570s with TURKS GPU came in to the market "without" any form of announcement regarding the changes from the manufacturers or even from AMD which is the supplier of the GPUs.

i personally met up with a stranger who owned a Powercolor HD5570 DD3 for the sake of seeking more information related to this. The card had exactly same hardware specs as mine (Sapphire HD5570 DDR3), HOWEVER, this guy had another HD5570 DD3 which is Sapphire but OLDER than what i have. release date indicated only the year 2009 for that card but the hardware specs indicated on GPU-Z were the real HD5570 specs. The guy bought the Powercolor thinking it would have the same performance as to Sapphire card but sadly it wasn't. He got in touch with Powercolor tech support only to be told that "they don't know the reason why there was a change in GPU"...

On another instance, I talked to a computer retail shop owner who lived just a few blocks away from my house and discussed with him the issue about the HD5570s... He willingly offered help and pulled out 2 Powercolor HD5570s DDR3 from the storage room and we tested the cards.. the hardware specs were the same... Turks GPU as well. It was that time that he discovered this issue, he called up his supplier of the cards and was told "we don't know there were changes"...

in summary, this TURKS GPU change on the HD5570s were produced and distributed "under the radar".... IT IS NOT FAKE. us owners of these cards with the turks are simply victims of the "marketing mayhem".

and since there's a couple of HD5570 Bios stored on the VGABIOS Database which belong to the REDWOOD GPU's, here's a download link to a TURKS bios of the HD5570. Perhaps you experts could dissect on this for information or perhaps innovation like making a modded bios for the turks gpu to somehow improve its performance.

now regarding "downclocked", ROPs for one has been reduced to 4 instead of 8. Memory clock appears to be "locked" at 667Mhz. I tried adjusting it to 700Mhz using Overdrive and the system became unstable.

Another thing i noticed is that before the CCC 12.4 update came, I was able to make use of the Overdrive feature.. now, it seems like it no longer functions as it should. adjusted the GPU Clock to 700 (650 default). opened Skyrim in Window mode and observed the gpu ratings from GPU-Z.. GPU clock remained at 650Mhz as Highest clocked recorded while i was playing the game.

hello guys i juz registered here to confirm this guy is telling the truth... cuz i bought today the same card.... powercolor hd5570 1gb 128bit ddr3. i have also the same problem. im going to try returning it back. cuz its too slow. geforce 210 is much better than it.
